	)

Calculate a 3d viewpoint and direction vector from 2d window coordinates. This ray_start is located at the viewpoint, ray_normal is the direction towards mval. ray_start is clipped by the view near limit so points in front of it are always in view. In orthographic view the resulting ray_normal will match the view vector.

Parameters:

ar	The region (used for the window width and height).
v3d	The 3d viewport (used for near clipping value).
out	The resulting normalized world-space direction vector.
mval	The area relative 2d location (such as event->mval, converted into float[2]).
ray_start	The world-space starting point of the segment.

	)

Calculate a 3d segment from 2d window coordinates. This ray_start is located at the viewpoint, ray_end is a far point. ray_start and ray_end are clipped by the view near and far limits so points along this line are always in view. In orthographic view all resulting segments will be parallel.

Parameters:

ar	The region (used for the window width and height).
v3d	The 3d viewport (used for near and far clipping range).
mval	The area relative 2d location (such as event->mval, converted into float[2]).
ray_start	The world-space starting point of the segment.
ray_end	The world-space end point of the segment.

Calculate a 3d direction vector from 2d window coordinates. This direction vector starts and the view in the direction of the 2d window coordinates. In orthographic view all window coordinates yield the same vector.

Parameters:

ar	The region (used for the window width and height).
mval	The area relative 2d location (such as event->mval converted to floats).
